    "subtitle": null,
    "abstract": "When people perform joint actions together, task knowledge\nis sometimes distributed asymmetrically such that one person\nhas information that another person lacks. In such situations,\ninterpersonal action coordination can be achieved if the\nknowledgeable person modulates basic parameters of her\ngoal-directed actions in a way that provides relevant infor-\nmation to the less knowledgeable partner. We investigated\nwhether systematic violations of predicted movement\nduration provide a sufficient basis for such communication.\nResults of a joint movement task show that knowledgeable\npartners spontaneously and systematically violated the pre-\ndictions of Fitts’ law in order to communicate if their partners\ncould not see their movements. Unknowing partners had a\nbenefit from these violations and more so if the violations\nprovided a good signal-to-noise ratio. Together, our findings\nsuggest that generating and perceiving systematic deviations\nfrom the predicted duration of a goal-directed action can\nenable non-conventionalized forms of communication during\njoint action.",
